Question

What is the inverse of the function f(x) = x – 12?​

Answer 1

Answer: f^-1(x) = x + 12.

Explanation:

1. Make f(x) = y.

y = x - 12

2. Switch the x and y variables:

x = y - 12

3. Solve for y by adding 12 on both sides:

x + 12 = y

4. Change y into f^-1(x):

f^1(x) = x + 12

I hope this is helpful! :)

Answer 2

f − 1 ( x ) = x + 12

Explanation:

To find the inverse, interchange the variables and solve for

y .
